NATO allies reaffirmed their ironclad commitment to Article 5 at the July 2026 Ankara summit while pledging sustained military aid to Ukraine, reflecting broad consensus on deterrence without direct confrontation. The Russia-Ukraine conflict has remained confined to non-member territory, with Russian operations focused on incremental gains inside Ukraine rather than verified armed attacks on alliance soil. Recent hybrid incidents, including drones entering Polish airspace and strikes near borders, prompted Article 4 consultations and defensive measures but fell short of triggering collective defense. European defense spending increases, U.S. burden-sharing signals, and alliance force posture enhancements on the eastern flank have strengthened deterrence in the near term. Absent a major escalation or territorial breach before year-end, these factors underpin trader expectations that invocation remains unlikely through December 2026.
